Create cool 2D games with a free game editor! · By Cosmo Myzrail Gorynych
docs.ctjs.rocks opened a time breach yesterday and showed docs for not-yet-released v1.3 :D It is now fixed; you can also find docs for your exact copy of ct.js in the expanding panel on the right edge of the window.
Thank , the problem is the version. I'm with 1.2.1 and there to use ct.room.borderX. I am going to compile from github for the new version
